The best sketch from an otherwise subpar episode of Portlandia featured Fred and Carrie doing another experiment with off-beat entrepreneurialism. In the past, we've seen them try to be movers who only biked across town or environmentalists who start their own recycling firm. This week, they were bike valets, in a sketch that highlights the contradiction between Portland's earthy bike culture and the service-y realm of valet parking. The business didn't work, but the sketch sure did.
